Active spacers are the core technology to achieve nanoscale precision and stability. It completely subverts the traditional concept of passive vibration isolation and elevates vibration control to a new level of “intelligent dynamic intervention”.
The core of the FABREEKA active spacer system is a high-speed closed-loop mechatronics control system.
First of all, precision sensing: the system’s built-in three-axis high-sensitivity acceleration sensor can monitor the vibration signal of the equipment base in real time and accurately. Its detection bandwidth covers 0.5Hz to 200Hz, and the resolution is as high as 0.1μm/s, which can capture extremely weak vibrations.
Secondly, intelligent algorithm: The built-in high-performance processor runs an advanced adaptive control algorithm, which can quickly analyze vibration characteristics and calculate accurate reverse offset force within 30 milliseconds.
Finally, precision execution: high-speed response piezoelectric or electromagnetic actuators instantly output a force equal to the vibration and in the opposite direction, which can offset vibration interference in real time and dynamically, creating a nearly absolutely static operating environment for the equipment.
The advancement of its structural design is reflected in the three-axis independent decoupling control and high integration.
FABREEKA active spacers have completely independent vibration control in the X, Y, and Z directions, avoiding the coupling effects that exist in traditional structures, ensuring that they can still provide precise and stable control in complex multi-directional vibration environments, and their positioning accuracy can reach ±0.05μm.
At the same time, the product adopts a fully sealed and integrated solid structure with a protection level of IP67. It can adapt to a wide temperature range of -40°C to 120°C, as well as harsh conditions such as dust, oil, and moisture in industrial sites. It provides a long-term, reliable, and stable automation operation foundation for semiconductor manufacturing, precision testing, optical experiments, and other scenarios that have extreme requirements for stability.
Air springs are the core component to solve ultra-low frequency vibration and heavy load support, and are the “flexible cornerstone” for the stable operation of heavy equipment and energy equipment.
The core technological breakthrough of ACE air springs is that through a unique fluid mechanics design, the natural frequency of the system has been successfully reduced to 0.5Hz – 1Hz, which is much lower than traditional steel springs (3 – 5Hz) and rubber pads (5 – 10Hz). This can effectively isolate the 1 – 10Hz ultra-low frequency vibration that is most harmful to equipment, and the vibration isolation efficiency is as high as more than 95%.
The capsule adopts a multi-layer composite structure and is made of high-strength rubber and aramid fiber braided materials. It has extremely high load-bearing capacity (up to 50 tons at a single point), excellent flexibility and anti-fatigue life, and can withstand long-term, heavy-load, and alternating working conditions.
Dynamic adaptive stability is a key advantage of ACE air springs.
The system integrates a high-precision automatic leveling control valve, which can sense the load changes of the equipment in real time and automatically adjust the air pressure in the air bag to maintain the equipment in a precise level state.
Whether the equipment is unloaded, fully loaded, or the load fluctuates violently during operation, stable support with “zero tilt and zero drift” can be achieved.
This feature is crucial to ensure the processing accuracy of heavy machine tools and the safe operation of energy equipment.
In addition, ACE air springs adopt a non-lubricated friction structure and patented sealing technology, which greatly reduces internal wear and gas leakage, extending the service life of the product to more than 15 years, significantly reducing the maintenance frequency and life cycle costs of heavy equipment, and providing a solid guarantee for the long-term automated operation of the equipment.
Vibration isolation pads and shock-absorbing pads are the most widely used basic vibration isolation components, and their performance directly determines the basic stability of industrial equipment.
FABREEKA and ACE’s vibration isolation pads and shock-absorbing pads are not simple elastomers, but high-performance damping elements developed based on in-depth materials science and engineering experience.
They adopt a composite structure design and are customized for different scenarios: For strong impact scenarios such as heavy machinery and crushers, a metal skeleton is combined with high-damping rubber to provide strong load-bearing capacity and impact absorption capabilities; for micro-vibration scenarios such as precision instruments and electronic equipment, special polymer materials with low hardness and high loss factors are used to effectively absorb medium and high-frequency vibrations without producing tiny friction noises.
Its long-term durability is a core competency.
Through exclusive material formula optimization, the product has excellent weather resistance: oil resistance, acid and alkali resistance, high and low temperature resistance, anti-aging, and anti-fatigue.
It can maintain stable vibration isolation performance in various harsh environments such as 24-hour continuous operation of industrial machinery, outdoor exposure of energy equipment, and long-term resting in laboratories, with a performance attenuation rate of less than 10% within 10 years.
This completely solves the problems of hardening, softening, cracking, and stiffness attenuation that occur with conventional products after long-term use, ensures the long-term stability of the equipment foundation, and provides an indispensable basic guarantee for the continuous, reliable, and efficient operation of industrial automation production lines.
In the energy industry, the stability of core equipment such as steam turbines, generators, fans, and pumps is directly related to the security and efficiency of energy supply.
FABREEKA and ACE’s air spring and vibration isolation pad combination solutions can effectively isolate ultra-low-frequency vibrations generated by equipment operation and reduce the fatigue stress of the basic structure.
In thermal power plants, after the application of ACE air springs, the vibration amplitude of the steam turbine is reduced by 80% and the basic life is doubled; in wind farms, FABREEKA shock pads effectively suppress tower resonance, extend the life of the gearbox by 50%, and significantly extend the maintenance cycle, providing core support for efficient, safe, and unattended automated operation of energy equipment.
In the field of heavy equipment, vibration is the main factor restricting processing accuracy and equipment life.
The composite system of FABREEKA active spacers and ACE air springs provides a perfect “precision + heavy load” solution for heavy machine tools, rolling mills, and presses.
The active spacer offsets the dynamic vibration during cutting and stamping in real time, controlling the processing accuracy to the micron level; the air spring carries hundreds of tons of dead weight and isolates foundation impacts.
An application case of a heavy-duty CNC rolling mill shows that the system has improved the plate thickness accuracy from ±0.5mm to ±0.05mm, increased production efficiency by 30%, and reduced equipment failure rates by 60%, directly promoting the precision and automation upgrade of heavy-duty manufacturing.
In industrial machinery automation production lines, stability directly determines production efficiency and product quality.
With its fast response and adaptive load capacity, ACE air springs have become an ideal choice for industrial robots, high-speed packaging machines, and servo presses.
In automated production lines such as automobile welding and electronic assembly, after the application of ACE air springs, the robot positioning accuracy has been improved from 0.2mm to 0.02mm, effectively avoiding welding defects, assembly deviations and detection misjudgments caused by vibration, increasing the OEE (overall equipment efficiency) of the production line by 15%, and significantly reducing the product defect rate, accelerating the process of intelligentization and unmanned production lines.
In laboratory scenarios, micro-vibration is the main cause of experimental failure and data distortion.
The FABREEKA active vibration isolation system can effectively isolate environmental interference and control vibration below 10nm/s².
In the semiconductor testing laboratory, its application reduces the positioning error of the photolithography machine from ±0.5μm to ±0.08μm; in the materials science laboratory, it provides a nanoscale stable platform for transmission electron microscopy, and the image resolution is increased to 0.1nm level, providing an extremely stable environment for cutting-edge scientific research and precision detection, and supporting the automation and high-precision development of scientific research experiments.

The dynamic response is fast. Under complex working conditions such as load fluctuations and environmental changes, the attitude is stable and drift-free, ensuring continuous and stable operation of the equipment. - Positioning accuracy advantages: Precision control capabilities from micron level to nanometer level cover all accuracy requirements for high-end manufacturing and precision scientific research. It is the core prerequisite for breaking through accuracy bottlenecks and realizing automated precision operations.
